Abstract

Patente de Invenção: ANTENA HELICOIDAL DE BANDA DUPLA. Uma antena helicoidal de banda dupla possibilita a operação em duas bandas de freq³ência. A antena helicoidal de banda dupla inclui duas antenas de banda única (1304, 1308), cada uma possuindo uma rede de alimentação (1804, 1808), um plano terra (412) oposto à rede de alimentação e um conjunto de um ou mais irradiadores (104A a 104D) que se estendem a partir da rede de alimentação. Uma aleta (1504) se estende a partir da rede de alimentação de uma das antenas, que provê uma alimentação para tal antena. A aleta (1504) também propicia uma trajetória ou via para que a corrente flua a partir dos irradiadores da segunda antena ao longo do eixo da segunda antena, desse modo aumentado a energia irradiada nas direções perpendiculares ao eixo. O plano terra de uma antena é usado como um anel de curto para a outra antena.Invention Patent: DOUBLE-BAND HELICOIDAL ANTENNA. A double band helical antenna allows operation in two frequency bands. The dual-band helical antenna includes two single-band antennas (1304, 1308), each having a supply network (1804, 1808), a ground plane (412) opposite the supply network and a set of one or more radiators (104A to 104D) extending from the supply network. A fin (1504) extends from the supply network of one of the antennas, which provides power for that antenna. The fin (1504) also provides a path or path for current to flow from the radiators of the second antenna along the axis of the second antenna, thereby increasing the energy radiated in directions perpendicular to the axis. The ground plane of one antenna is used as a short ring for the other antenna.
